AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
307 AM MDT THU MAY 24 2012

.SYNOPSIS...A COOL SURFACE RIDGE WILL RESIDE ACROSS THE REGION
TODAY. AN APPROACHING PACIFIC STORM SYSTEM WILL BRING STRONG
WINDS TO MUCH OF THE AREA FRIDAY...BEFORE THIS SYSTEM SWEEPS
ACROSS UTAH SATURDAY. DRY AND INCREASING MILD WESTERLY FLOW WILL
PREVAIL FOR THE LATTER HALF OF THE WEEKEND INTO NEXT WEEK.

&&

.DISCUSSION...BROAD LONGWAVE TROUGH ENCOMPASSES MUCH OF THE
WESTERN CONUS/WESTERN CANADA EARLY THIS MORNING...WITH A SERIES OF
SHORTWAVE FEATURES ROTATING THROUGH THE LARGER SCALE FLOW. WAVE
WHICH BROUGHT SHOWERS TO PORTIONS OF NORTHERN UT CONTINUES TO
TRANSLATE EASTWARD THROUGH THE CENTRAL ROCKIES AND AWAY FROM THE
FORECAST AREA. ASSOCIATED SURFACE FRONT PUSHED THROUGH SOUTHERN UT
DURING THE DAY WEDNESDAY...AND IS CURRENTLY LAID OUT ACROSS
NORTHERN NM/AZ BACK INTO SOUTHERN NV.

SURFACE RIDGING IN THE WAKE OF THIS FRONT RESIDES ACROSS NORTHERN
UT...AND WILL REMAIN ACROSS THE FORECAST AREA TODAY MAINTAINING A
FAIRLY COOL AND STABLE AIRMASS. ANY CHANCE FOR PRECIPITATION LOOKS
TO REMAIN CONFINED TO THE FAR NORTH NEAR THE ID BORDER.

CURRENTLY HAVE A HARD FREEZE WARNING FOR THE WASATCH MOUNTAIN
VALLEYS...HOWEVER CONSIDERABLE CLOUD COVER ALONG WITH LINGERING
LOW LEVEL MOISTURE HAVE KEPT TEMPS ELEVATED IN THE UPPER 30S/LOWER
40S THUS FAR. WILL CONTINUE TO MONITOR TEMPS...AND IF SKIES TO NOT
CLEAR OUT BEFORE SUNRISE WILL LIKELY CANCEL WARNING.

ATTENTION THEN TURNS TO VIGOROUS SHORTWAVE TROUGH CURRENTLY OFF
THE BC COASTLINE NEAR 135W. THIS WAVE IS FORECAST TO QUICKLY DIG
SOUTH ALONG THE PACIFIC NORTHWEST COAST TODAY BEFORE DROPPING INTO
CA AND THE WESTERN GREAT BASIN TONIGHT THROUGH FRIDAY. AS THIS
WAVE DIGS ALONG THE SIERRA TONIGHT SURFACE FRONT IS EXPECTED TO
QUICKLY LEFT BACK TO THE NORTH LEAVING MUCH OF THE FORECAST AREA
IN THE WARM SECTOR FRIDAY.

VERY STRONG FLOW ALOFT DOWNSTREAM /700MB FLOW OF 40-50 KTS FRIDAY
AFTERNOON/ COMBINED WITH TIGHTENING SURFACE GRADIENT WILL SUPPORT
STRONG TO SEVERE WINDS ACROSS MUCH OF CENTRAL AND SOUTHERN UT
FRIDAY AFTERNOON THROUGH FRIDAY EVENING. THIS WILL LIKELY HAVE A
SIGNIFICANT IMPACT ON HOLIDAY TRAVEL...PARTICULARLY WITH A LARGER
VOLUME OF HIGH PROFILE VEHICLES INCLUDING CAMPERS...RVS AND
TRAILERS. WILL GO AHEAD AND ISSUE HIGH WIND WATCH FOR THESE AREAS.
THESE STRONG WINDS WILL ALSO EXACERBATE FIRE WEATHER CONDITIONS
ACROSS CENTRAL/SOUTHERN UT...WHERE A RED FLAG WARNING REMAINS IN
EFFECT. SURFACE PRESSURE TROUGH LOOKS TO STALL ACROSS NORTHWEST UT
FRIDAY AFTERNOON...WHICH SHOULD RESULT IN MUCH LIGHTER WINDS
ALONG/NORTH OF I-80. STRONG WINDS WILL REMAIN POSSIBLE INTO
SATURDAY...PARTICULARLY ACROSS EASTERN PORTIONS OF THE AREA AHEAD
OF THE SURFACE FRONT.

UPPER WAVE LOOKS TO EJECT ACROSS THE EASTERN GREAT BASIN
SATURDAY...PUSHING NORTH-SOUTH ORIENTED COLD FRONT THROUGH THE
FORECAST AREA. BEST LARGE SCALE ASCENT LOOKS TO BE DISPLACED
NORTHWEST OF THE AREA...HOWEVER TWO PARTS TO THIS SYSTEM LOOK TO
BRING PRECIPITATION TO PRIMARILY NORTHERN UTAH. THE FIRST CHANCE
COMES SATURDAY AS THE SURFACE FRONT LOOKS TO LIGHT UP ALONG/EAST
OF THE WASATCH RANGE SATURDAY AFTERNOON AS JET STRENGTHENS
OVERHEAD...WHILE THE PASSAGE OF THE TRAILING MID LEVEL TROUGH
BRINGS ANOTHER ROUND TO THE NORTH SATURDAY NIGHT INTO EARLY
SUNDAY. HAVE ADJUSTED GOING POPS TO FIT THIS TREND.

IN THE WAKE OF THIS WAVE A DRY AND INCREASINGLY MILD WESTERLY FLOW
WILL PREVAIL FOR THE SECOND HALF OF THE HOLIDAY WEEKEND INTO THE
MIDDLE OF NEXT WEEK.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY. LIGHT NORTHERLY WINDS ARE EXPECTED TO SHIFT TO THE SOUTHEAST
BETWEEN 10Z AND 12Z BEFORE RETURNING TO THE NORTHWEST BETWEEN 16Z
AND 18Z. HOWEVER...THERE IS A 30 PERCENT CHANCE THAT WINDS WILL BE
LIGHT AND VARIABLE OR LIGHT NORTHERLY THROUGH THE MORNING HOURS.

&&

.FIRE WEATHER...SOUTHWEST WINDS WILL BEGIN TO INCREASE TODAY AS A
PACIFIC NORTHWEST STORM SYSTEM MOVES ONSHORE. COMBINED WITH THE DRY
AIRMASS...SOME CRITICAL FIRE WEATHER CONDITIONS WILL OCCUR OVER FAR
SOUTHERN UTAH...WHERE A RED FLAG WARNING IS IN EFFECT. AS THE SYSTEM
APPROACHES ON FRIDAY...WINDS WILL BECOME QUITE STRONG OVER MUCH OF
THE CENTRAL AND SOUTHERN PORTIONS OF THE DISTRICT...RESULTING IN
WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS. AS THE SYSTEM ENTERS
THE STATE ON SATURDAY...RELATIVE HUMIDITIES WILL RISE.
HOWEVER...SEVERE FIRE WEATHER CONDITIONS MAY PERSIST OVER SOUTHEAST
UTAH. WETTING RAINS ARE POSSIBLE SATURDAY INTO EARLY SUNDAY ACROSS
PRIMARILY NORTHERN UTAH AS THE SYSTEM MOVES ACROSS THE DISTRICT.
WEAK HIGH PRESSURE IS EXPECTED TO DEVELOP FOR EARLY NEXT WEEK.

COMBINATION OF LOW DAYTIME HUMIDITY AND GUSTY WEST WINDS.

THERE IS A POTENTIAL FOR VERY STRONG SOUTH WINDS ACROSS MUCH OF
THE OUTLOOK AREA FRIDAY...AHEAD OF A FAIRLY POTENT STORM SYSTEM
WHICH IS EXPECTED TO MOVE INLAND FROM THE GULF OF ALASKA. THERE IS
STILL SOME UNCERTAINTY REGARDING THE TRACK OF THIS SYSTEM...WHICH
WILL HAVE A LARGE INFLUENCE ON BOTH THE STRENGTH OF THE WINDS
FRIDAY AS WELL AS ANY PRECIPITATION CHANCES LATE FRIDAY THROUGH
